Hair band



FIG. 1 is a perspective view of the hair band;

FIG. 2 is a front view of the hair band, which is identical to the backview of the hair band;

FIG. 3 is a left view of the hair band, which is identical to the topview and the right view of the hair band; and,

FIG. 4 is a bottom view of the hair band.

I claim the ornamental design for a hair band, as shown and described.
